LOCKING MECHANISM FOR COIN-RECEPTACLES.

Specification of Letters Tatent.

Patented Oct. 20, 19013.

Application filed August 8, 1907. Serial No. 387,678.

To all whom it may concern:

Be it known that I, WILLIAM H. WOOL-- UMS, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Looking Mechanism for Coin-Receptacles, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to locking mechanism for coin receptacles particularly for coin receptacles as disclosed in my Patent No. 341,756 dated J an. 22, 1907.

In the accompanying drawing Figure 1 is a front view of the receptacle to which my invention is shown applied; Fig. 2 is an inside view of the body part, the cover part being removed; Fig. 3 is an inside view of the cover part; Fig. 4 is a view of the looking end of the closed receptacle; Fig. 5 is a view of the locking end of the body part;

' Fig. 6 is a view of the locking end of the cover part; Fig. 7 is a view of the entrance end of the closed receptacle; Fig. 8 is a view of the entrance end of the body part; Fig. 9 is a view of the entrance end of the cover part; Fig. 10 is a sectional view taken on line 101O Fig. 3; Fig. 11 is a sectional view taken on line 11-11 Fig. 3; Fig. 12 is an inside view of the locking end with the locking plate mechanism removed; Fig. 13 is a plan view of the locking plate; and Fig. 14 is a plan view of the key for the receptacle.

The body part 1 is stamped integral and is in the form of a shallow rectangular box, the edge 2 being offset inwardly the thickness of the sheet metal to form the shoulder or ledge 3 and the retaining flange 4:, and the blank for the body part when stamped has the extension 5 from the center of whose edge extends the locking detent 6 for the lock mechanism. lVhen the blank is formed, this extension projects horizontally inwardly to lie in the plane of the shoulder 3 and the hook 6 extends outwardly as shown in Figs. 2, 5 and 10. The detent has the neck part 7 and the hook part 8, the outer edge 9 of the hook part being rounded as shown.

The cover part 17 is similar in shape to the body part, being also stamped integrally, its edge 18, when the parts are brought together, fitting about the flange 4 and against the shoulder 3 of the body part, as shown in The locking plate 26 has the hole 27 and an eyelet or hollow rivet 2.8 is engaged in the holes 23 and 27 to pivot the locking plate to the shelf. At the outer edge of the looking plate an extension 28 is turned downwardly to form a stop for engaging against the edge 29 of the opening 22. A tongue 30, also at the outer edge of the locking plate, is turned downwardly and then horizontally outwardly across the right half of the opening 22 so that its end engages under, and is held and guided by the edge 31 of the opening 22, the normal position of the looking plate and extensions being best shown in Figs. 3, 10 and 11. At the inner right hand corner of the locking plate is an arm 32 terminating in a hook 333 for receiving one end of the tension spring 34, whose other end engages the hook 35 at the end of the arm 36 extending toward the right from the edge of the shelf 20. This spring serves to hold the locking plate in its normal position with the stop 28 against the edge 29 and the locking tongue extending across the opening 22.

When the receptacle halves are brought together the rounded head 9 of the hook 8 engages against the locking tongue 30 and the edge 29 forcing the tongue to the right and causing the locking plate to rotate against the tension of the spring 34. When the hook arrives below the locking tongue, the tongue is released and the locking frame is returned to its normal position by the force of the spring to engage the locking tongue under the hook, and the parts are then looked together. Upon rotation of the locking plate, the locking tongue enters and travels in the curved slot 24:, the rotation of the locking plate being limited by the engagement of the tongue with the end of the slot. The downward pressure of the look ing hook on the tongue is sustained by the locking plate which is pivoted on top of the shelf 20, while the upward strain on the tongue, when an attempt is made to force the lock, is, in greater part, resisted by the engagementof the tongue end under the shelf, strain on the rivet being thus reduced to a minimum.

The key is shown in Fig. 14:. The shank 36 extends from the head 37, and terminates in the point 38, an L shaped extension 39 giving the point 40 parallel with point 39. The key-hole in the cover part comprises the circular opening 4-1 and the slot 42, the opening being in register with the hollow rivet 28 which pivots the locking plate. hen the key is inserted, the point 38 passes through opening a1 and into the rivet while the point 40 engages the under side of the shelf 20. The key is then turned counterclockwise until the point L0 drops into the opening and against the side of the locking tongue Further turningof the key then causes the locking plate to be rotated and the locking tongue disengaged from the hook whereupon the receptacle parts may be separated. The .key is then pulled slightly to withdraw the point 40 from the opening 22 and is then rotated and withdrawn through the key-hole. The slot 42 of the key-hole may extend in any direction, but preferably away from the opening 22 to prevent picking of the lock.

I thus provide locking mechanism particularly adaptable to coin receptacles but which. may also be applied to other kinds of receptacles. The locking mechanism is very simple and inexpensive, all the parts being stamped from sheet material.

I desire to secure the following claims by Letters Patent.

1. In locking mechanism for coin receptacles having a body part and a cover part, the combination of a locking hook extending from an edge of the-body part and formed integral therewith, a shelf extending horizontally inwardly from the corresponding edge of the cover part and formed integral therewith, there being an opening through the shelf, a locking plate rotatably pivoted on top of the shelf and having a locking tongue extending normally through and across the opening with its end engaging the under side of the shelf, and a spring tending to hold the plate and tongue in the normal position, said hook on the body part passing through the opening and against the tongue when the receptacle parts are brought together to be closed whereby the locking plate is rotated and eventually returned when the parts are closed to bring the tongue into locking engagement with the hook to thereby lock the receptacle.

2. In locking mechanism for coin receptacles having a body part and a cover part, the combination of a locking hook extending from an edge of the body part, a shelf extending from the correspondmg edge of the cover partand having a rectangular opening,

a locking member pivoted on top of the shelf and extending downwardly through the opening and then forwardly across part of the opening, spring means tending to hold the locking member in the normal position, and stops for limiting the movement of the locking member, said hook passing through the opening when the parts are brought together and moving aside the locking member, which locking member is brought back to its normal position by the spring means when the parts are closed to engage the hook to lock the parts together.

3. In locking mechanism for coin receptacles having a body part and a cover part, the combination of a hook for extending from one of the parts, a shelf for extending from the other part and having a rectangular opening, a locking plate, a hollow rivet pivoting the locking plate to the shelf, a locking tongue extending from the looking plate across the opening, spring means for resisting rotation of the plate, said hook being adapted for passing through the opening when the receptacle parts are brought together to engage the tongue to cause rotation of the plate, said plate being returned by the spring means when the hook has passed through the opening whereby the locking tongue is brought into locking engagement with the hook, a key for passing through a when the receptacle parts are brought tokey-hole in one of the receptacle parts, said key having a pivot point for engaging in the hollow rivet, and an extension on said key for engaging with the tongue to rotate the plate to carry the tongue away from and to release the hook.

4. In locking mechanism for coin receptacles, the combination of a supporting shelf having an opening, a plate pivoted on said shelf, a locking tongue extending from said plate through'and across the opening to lie below the shelf, an extension from the plate, said plate, extension and tongue being stamped integral from sheet material, an extension from the shelf, a spring engaging the extensions and tending to hold the tongue in a normal position, and a locking hook adapted to enter the opening to move aside the tongue and to be engaged by the tongue when restored by the spring to be locked against withdrawal from the opening.

In witness whereof, I hereunto subscribe my name this sixth .day of August A. D., 1901.
